BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to novel solid pharmaceutical compositions andprocesses for the bulk production of said compositions. This inventionalso provides methods of using the pharmaceutical compositions in thetreatment of cancer.

2. Background of the Invention

In general, solid pharmaceutical compositions comprise apharmaceutically active ingredient, such as a small molecule, admixedwith pharmaceutically acceptable excipients in amounts appropriate tomaintain the original activity of the active ingredient. Thesecompositions are typically delivered to patients in the form of tabletsor capsules.

Examples of particular active ingredients can be found in U.S. Pat. No.7,572,784, US Publication No. 2008/0045501, US Publication No.2008/0167292, and U.S. Application No. 61/306,047, filed Feb. 19, 2010,hereby incorporated by reference in their entirety, which disclosecompounds that inhibit Aurora kinase enzymes. These applicationsadditionally disclose methods for the preparation of these compounds,pharmaceutical compositions containing these compounds, and methods forthe prophylaxis and therapy of diseases, disorders, or conditionsassociated with overexpression and/or amplification of Aurora kinases,including, but not limited to, cell proliferative disorders such ascancer.

Important considerations during the manufacturing of solidpharmaceutical compositions include preserving the crystal form of theactive ingredient and maintaining the active ingredient's chemical andphysical stability. Manufacturers generally target a 2- to 3-year shelflife for pharmaceutical compositions.

Thus, there is a need to develop solid pharmaceutical compositions thatare stable and have favorable bioavailability. In particular, there is aneed for solid pharmaceutical compositions comprising Aurora kinaseinhibitors.

These methods offer analternate approach to processing wet granulation based formulations thatrequire a buffer for bioavailability as compared to prior art methods.It has been determined that the order of addition of excipients duringthe granulation process affects the drug product's dissolution whenstored for stability studies.

In another aspect, the invention provides pharmaceutical compositionsthat may be prepared by such methods, comprising the active ingredients,buffers and additional excipients as described herein.

In yet another aspect, the invention provides methods for treatingdisorders using the pharmaceutical compositions as described herein.

The patent and/or scientific literature referred to herein establishesknowledge that is available to those with skill in the art. Unlessotherwise defined, all technical and scientific terms used herein havethe same meaning as commonly understood by one of ordinary skill in theart to which this invention relates. Although methods and materialssimilar or equivalent to those described herein can be used in thepractice or testing of the present invention, the preferred methods andmaterials are described herein. The issued patents, applications, andreferences that are cited herein are hereby incorporated by reference tothe same extent as if each was specifically and individually indicatedto be incorporated by reference. In the case of inconsistencies, thepresent disclosure, including definitions, will control. In addition,the materials, methods, and examples are illustrative only and are notintended to be limiting.

DEFINITIONS

The term “active ingredient” is used herein to mean a component of apharmaceutical composition that is pharmaceutically or physiologicallyactive.

The term “pharmaceutically acceptable excipient” is used herein to referto a material that is compatible with a recipient subject, preferably amammal, more preferably a human, and is suitable for delivering anactive agent to the target site without terminating the activity of theagent. The toxicity or adverse effects, if any, associated with theexcipient preferably are commensurate with a reasonable risk/benefitratio for the intended use of the active ingredient. Classes ofpharmaceutically acceptable excipients include, but are not limited to,surfactants, binders, disintegrants, lubricants, glidants, fillers, andbuffers.

The term “about” is used herein to mean approximately, in the region of,roughly, or around. When the term “about” is used in conjunction with anumerical range, it modifies that range by extending the boundariesabove and below the numerical values set forth. In general, the term“about” is used herein to modify a numerical value above and below thestated value by a variance of 10%.

As used herein, “w/w %” is used to mean by weight as a percentage of atotal weight that is used as the basis for calculating the weightpercentage of an individual component. By way of example, for a bulkcomposition, the w/w % of an individual component may be calculated as apercentage of the total weight of all of the components of the bulkcomposition. By way of another example, for a single oral dosage form,the w/w % of an individual component may be calculated as a percentageof the total weight of all of the components of the single oral dosageform. For example, when the single oral dosage form is a coated tablet,the total weight may be the total weight of all the components of thecoated tablet including the coating(s). Alternatively, the total weightmay be the total weight of all the components of the tablet notincluding the coating(s)

As used herein, the term “comprises” means “includes, but is not limitedto.”

As used herein, a “subject” is preferably a bird or mammal, such as ahuman, but can also be an animal in need of veterinary treatment, e.g.,domestic animals (e.g., dogs, cats, and the like), farm animals (e.g.,cows, sheep, fowl, pigs, horses, and the like) and laboratory animals(e.g., rats, mice, guinea pigs, and the like).

As used herein, “treating” or “treatment” means prevention, partialalleviation, or cure of a disease, disorder or condition.

As used herein, “therapeutically effective amount” is meant to describean amount of a compound, composition, medicament or other activeingredient effective in producing the desired therapeutic effect.

As used herein, the term “Aurora kinase” refers to any one of a familyof related serine/threonine kinases involved in mitotic progression. Avariety of cellular proteins that play a role in cell division aresubstrates for phosphorylation by Aurora kinase enzymes, including,without limitation, histone H3, p 53, CENP-A, myosin II regulatory lightchain, protein phosphatase-1, TPX-2, INCENP, survivin, topoisomerase IIalpha, vimentin, MBD-3, MgcRacGAP, desmin, Ajuba, XIEg5 (in Xenopus),Ndc10p (in budding yeast), and D-TACC (in Drosophila). Aurora kinaseenzymes also are themselves substrates for autophosphorylation, e.g., atThr288. Unless otherwise indicated by context, the term “Aurora kinase”is meant to refer to any Aurora kinase protein from any species,including, without limitation, Aurora A, Aurora B, and Aurora C,preferably Aurora A or B. Preferably, the Aurora kinase is a humanAurora kinase.

The term “Aurora kinase inhibitor” or “inhibitor of Aurora kinase” isused to signify a compound having a structure as defined herein, whichis capable of interacting with an Aurora kinase and inhibiting itsenzymatic activity. Inhibiting Aurora kinase enzymatic activity meansreducing the ability of an Aurora kinase to phosphorylate a substratepeptide or protein. In various embodiments, such reduction of Aurorakinase activity is at least about 50%, at least about 75%, at leastabout 90%, at least about 95%, or at least about 99%. In variousembodiments, the concentration of Aurora kinase inhibitor required toreduce an Aurora kinase enzymatic activity is less than about 1 μM, lessthan about 500 nM, less than about 100 nM, or less than about 50 nM.
